Gene Therapy Brings ALS Cure One Step Closer

Researchers at the University of Sheffield have moved one step closer to a gene therapy that could silence the faulty SOD1 gene responsible for triggering a form of motor neuron disease (MND) also known as amyotrophic lateral sclerosis (ALS).
Scientists from the Sheffield Institute for Translational Neuroscience (SITraN) have begun groundbreaking research to develop a gene therapy that, if successful, could cure one form of the devastating neurological disease which affects more than 5,000 people in the UK.
Until now, all available treatments and drug-trials conducted across the world have failed to effectively halt the progression of the condition. Riluzole, the only drug that has demonstrated a survival benefit, prolongs life for just three to six months and may not be effective in all patients.
Professor Mimoun Azzouz, a leading gene therapy scientist and chair of Translational Neuroscience, said: “This pioneering project has the potential to deliver the first meaningful neuroprotective therapy for MND, offering a real beacon of hope for patients and their families living with this cruel disease. Silencing the SOD1 gene that is associated with 20 percent of familial MND cases may be as close as we can get to a cure for MND in the near future. Our ultimate goal is to get the gene therapy for SOD1-related MND into the clinic as soon as possible. Gene therapy is regarded as an innovative technique with huge potential for the treatment of neurological conditions including MND."
Azzouz added: “We plan to use the gene therapy initially in an inherited form of MND caused by alterations in a gene known as SOD1, but we intend to broaden the approach to other groups of MND patients in the future. ALS/MND is characterized by the progressive loss of nerve cells (motor-neurons) that connect the brain with the muscles to control movements. As the disease progresses, patients may lose the ability to walk, move, eat, talk and finally breathe.”
This pioneering research, funded by a donation of 2.2 million pounds from an anonymous donor, is jointly led by Azzouz, a gene therapy expert, and world-leading MND expert Professor Dame Pam Shaw– the founder of SITraN.
“MND is considered a rare disease and therefore tends to be overlooked in terms of funding for the development of new therapies,” said Shaw. “This emphasizes the importance of the extremely generous donation made by a philanthropist based in the USA, for our gene therapy research program and for our patients with MND who don’t have time to wait.”
“The experience that we have accumulated with our gene therapy and clinical trial programs at SITraN is crucial to develop this new therapy for patients with ALS/MND. We plan submission for regulatory approval by August 2015, for permission to take this therapy to patients in the clinic,” Shaw added.
Researchers at SITraN will now start a large preclinical study before the first-in-human clinical trial. The team are also currently preparing for the first ever UK gene therapy trial in humans for Spinal Muscular Atrophy (SMA) which is a childhood form of MND.
